Description
(バインダー)
コータックスLH-404:東レ・ファインケミカル株式会社製
(粒子)
ARX-15:積水化成品工業株式会社製、樹脂粒子、粒径16.8μm
SIO07PB:株式会社高純度化学研究所製、二酸化珪素、粒径0.8μm
S42XHS:住友スリーエム株式会社製、中空シリカ、真密度0.42g/cm3
WZ-501:株式会社アムテック製、酸化亜鉛単結晶パナテトラ、平均繊維長10μm
試料作製は、粒子、樹脂及び溶剤を加えて粘度を調節した後に、ハイブリッドミキサーを用いて混合した。
(放熱評価方法)
面状発熱体ポリイミドヒーターFL−HEATNo.6(シンワ測定株式会社)をアルミ板(50mm×80mm、t:2mm)で挟む。アルミ板の表面に熱電対をアルミ板用はんだで接着する。アルミ板表面に調合した試料を塗布し、60℃30分で加熱乾燥させ、膜厚が30μmになるように塗布した。試料を25℃に設定した恒温槽中央に静置し、ヒーターに6Wを印加し、アルミ板表面の温度変化を測定した。ヒーターは一定の熱量を発生しているので、熱放射材料の放熱効果が高いほど、ヒーターの温度もしくはアルミ板表面温度は低下する。すなわち、ヒーターの温度もしくはアルミ板表面温度が低くなるほど放熱効果が高いといえる。
(比較例1)
コータックスLH-404をアルミ板にハケ塗布でコーティングし、60℃30分で加熱乾燥させ、膜厚が30μmになるようにコーティング膜を形成した。

(比較例3)
コータックスLH-404に対して、HS42XHS中空シリカ5W%を容器に入れハイブリッドミキサーを用いて混合し、アルミ板にハケ塗布でコーティングし、60℃30分で加熱乾燥させ、膜厚を30μmになるように熱放射性コーティング膜を形成した。
